Similar characters of reference are used to indicate the same partsthroughout the several views.

This invention employs four shiftable blocks of special shapes for eachof the four crossings of the rails. These blocks are shiftableautomatically by the flanges of passing wheels. The flange of a wheelshifts two of the blocks and the shifted blocks shift the other twoblocks. The blocks form parts of the treads for the wheels and theflanges of the wheels project far enough in advance so that the blocksare shifted inplace for the treads before the treads run on the blocks.

The drawings show blocks 1, 2, 3, and 4 and a quadrangular frame 9 isrigidly mounted on a 7 base 5 for preventing displacement of the blocks.The holdingframe 9 has passage ways forthe four approaches of the wheelflanges and for the four exits of the wheel flanges and the holdingframe 9 has its central part cut awayto form 7 the block assembly space23. The holding frame has portions 5, 6, 7, and 8 which form partsof thetreads for the wheels. The treads of the wheels roll 011- of the rails24 onto the portions 5,

s, '1, and s. The blocks 1, 2, 3, and 4 have raised triangular portions10 which cooperate with the surfaces 5, 6, 7, and 8 to complete the railtreads across the crossings. The blocks 1, 2, 3, and 4 have base membersl3 which project under and support the surface members 5, 6, 7, and 8 ofthe holding frame 9. The blocks 1, 2, 3, and 4 are supported and slideon a base plate 5' which may be made'rigid with a bed plate 22. The

blocks 1, 2, 3, and 4 have beveled approaches 11 to act as guides forthe wheel flanges to start in between two blocks. These beveledapproaches are at all four approaches'of the wheels. The under-cuts inthe members 5, 6, '7, and 8 for the members 13 of the blocks are shownat 25. The wheel flange 32 actuates the blocks 1, 2, 3, and 4 and theflange members 13 are projected under the members 5, 6, '7, and 8 as faras the boundtuate another block. Disks 15 and 16 are ro- 'tatablymounted on anupr'ight spindle 28. The

peaks of the blooksil, 2, 3, and 4 are under-cut so that the disks 15and 16 will project slightly thereunder. Recesses 19 are formed in theblocks 1-4 and the disks 15 and 16 have lugs no holding frame.

17 and 18 which are adapted to project into the recesses 19. By suchconstruction, when one of the blocks 1-4 is actuated, it will actuateanother block automatically. Consider Figs. 3 and 5. The lugs 18 occupythe recesses 19 in blocks 2 and 4 and the lugs 17 occupy the recesses inblocks 1 and 3. If the wheel flange 32 enters at the b'ottom of Fig.3,the blocks 3 and 4 will be spread by the flange 32. The block 3 byreason of the recess 19 will move the lug 17 and the lug 17 on theopposite side of the disk 15 will actuate the block 1 and the block 4 byreason of the recess 19 therein will actuate the lug 18 and so actuatethe disk 16 and the disk 16 by reason of the lug 18 on the opposite sideof disk 16 will actuate the block 2. All four blocks 1-4 will be spreadfor the passage of the wheel flange 32 and simultaneously the treadsurfaces 10 will be brought in line with surfaces 6 and 7 to completecontinuous track surfaces for the tread of the. passing wheel from therails 24 or from the rails 20 and 21. Similar operations take place whena wheel flange enters any one of the approaches to the crossing andstrikes the beveled surfaces 11 of the blocks 1-4.

In these operations the blocks 1-4 are guided by the flanges 13 movingalong the boundary walls 14 within the cut-outs or spaces 25 in the mainframe 9, and also by the portions 10 of the blocks moving against theedges of the tread supporting members 5, 6, 7, and 8 of the main Thearms 27 are limited in movement and stop against the abutments 29 of themain holding frame 9. The blocks 1-4 have lips 31 which move against oralong the sides of an abutment 30 which is rigid with the bed plate 5.The flanges of the wheels tend to force the blocks 1-4 outwardly and theabutment 38 and the lips 31 serve further to prevent inward movement ofthe blocks 1-4. The abutment 30 thus serves as an additional guide forthe blocks 1-4. The guard rail 33 is a necessary element in theoperations of the crossings. The guard rail sections abut against themain holding frame 9 in the same manner as the rails 24. The mainholding frame 9 is secured to the base plate 5 by bolts 34 and nuts 35.
